Currently when the dataset is in use we can't receive snapshots.
zfs send test/1@asd | zfs recv -FM test/2
cannot unmount '/test/2': Device busy
This commits add option 'M' which attempts to forcibly unmount the
dataset. Thanks to this we can enforce receiving snapshots in a
single step.
Note that this functionality is not supported on Linux because the
VFS will prevent active mounted filesystems from being unmounted,
even with the force option. This is the intended VFS behavior.

openzfs/zfs@d8d418ff0c
We've observed that on some highly fragmented pools, most metaslab
allocations are small (~2-8KB), but there are some large, 128K
allocations. The large allocations are for ZIL blocks. If there is a
lot of fragmentation, the large allocations can be hard to satisfy.
The most common impact of this is that we need to check (and thus load)
lots of metaslabs from the ZIL allocation code path, causing sync writes
to wait for metaslabs to load, which can take a second or more. In the
worst case, we may not be able to satisfy the allocation, in which case
the ZIL will resort to txg_wait_synced() to ensure the change is on
disk.
To provide a workaround for this, this change adds a tunable that can
reduce the size of ZIL blocks.

By default, zpools may not be backed by zvols (that can be changed with the
"vfs.zfs.vol.recursive" sysctl). When that sysctl is set to 0, the kernel
does not attempt to read zvols when looking for vdevs. But the zpool command
still does. This change brings the zpool command into line with the kernel's
behavior. It speeds "zpool import" when an already imported pool has many
zvols, or a zvol with many snapshots.

This will be used in libbe in place of the internal zmount(); libbe only
wants to be able to mount a dataset at an arbitrary mountpoint without
altering dataset/pool properties. The natural way to do this in a portable
way is by creating a zfs_mount_at() interface that's effectively zfs_mount()
+ a mountpoint parameter. zfs_mount() is now a light wrapper around the new
method.
The interface and implementation have already been accepted into ZFS On
Linux, and the next commit to switch libbe() over to this new interface will
solve the last compatibility issue with ZoL. The next sysutils/openzfs
rebase against ZoL should be able to build libbe/bectl with only minor
adjustments to build glue.

After the allocation_classes feature was integrated, one can no longer add a
log device to a pool unless that feature is enabled. There is an explicit check
for this, but it is unnecessary in the case of log devices, so we should handle
this better instead of forcing the feature to be enabled.

FreeBSD notes.
I faithfully added the new -g, -L, -P flags, but only -g does something:
vdev GUIDs are displayed instead of device names. -L, resolve symlinks,
and -P, display full disk paths, do nothing at the moment.
The use of special vdevs is backward compatible for read-only access, so
root pools should be bootable, but exercise caution.

The DOF file output by dtrace -A contains only the loadable sections.
However, as it was created by a call to dtrace_dof_create() without
flags, the original DOF was created with the loadable sections. The
result is that the DOF includes the section headers for the unloadable
sections (COMMENTS and UTSNAME) without these sections actually being
present. This is inconsistent.
A simple change to anon_prog() ensures that the missing sections are
present in the outputted DOF. Alternatively, the call to
dtrace_dof_create() could pass the DTRACE_D_STRIP flag stripping out the
loadable sections. As the unloadable sections contain info useful for
debugging purposes they haven't been stripped.

'zpool sync' will return when data has hit the main storage instead of
potentially just the ZIL as is the case with the 'sync(2)' cmd.

This patch modifies the zfs_ioc_snapshot_list_next() ioctl to enable it
to take input parameters that alter the way looping through the list of

throw away some of the snapshots returned by the ioctl to a range of
snapshots that these functions actually use. This improves efficiency
and execution speed for some rollback and send operations.
